8 Operation Details
8.1. Basic Function
Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air temperature.
8.1.1. Internal Setting Temperature
Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes. These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit.

Then, a directed changed part changes frequency to the present frequency.
8.1.2.1.2. Initial frequency determination
After a starting control end, initial frequency (absolute value) is determined.
However, a FcMAX domain judges instantly.
8.1.2.1.3. Change frequency determination
When (Suction-setup) is +0.5deg, directions of Fcmax came by the mentioned initial frequency.
Fcmax continued until it reaches. (If other directions came by protection control, priority is given)
When room temperature is reached, it shifts to relative control after moving to change frequency.
The following operation determines change frequency.
The Hzkirikae = present condition frequency * Inclines and it is calculation.
Inclination = lapsed time to remote control attaintment (Minute)
Inclination 0-60 60 - 90 90
Inclination coefficient 80% 90% 100%
1. The present frequency is real operation frequency.
2. When change directions come out with remote control after starting, continue calculation as it is.
The time to room temperature attainment is calculated.
3. When remote control directions were changed before room temperature attainment and below room temperature attainment
temperature becomes
With initial frequency, it is considered as change frequency.

CS-E9DKEW CU-E9DKE / CS-E12DKE W CU-E12DK E
8.1.2.1.4. The frequency changed method
1. After shifting to relative control, (intake-setting) is every 60 seconds, A tap is adjusted according to the domain and frequency changes relatively to present condition.
2. Intake-setting to other domains by load sudden change (remote control setting, open air introduction, etc.). When it moves, it has the following renewal of data, an addition and subtraction tap is switched.
3. When the load change was further carried out and suction-setup separates the domain of relative control, it goes to the clause of initial frequency and operation frequency is determined.
8.1.2.2. The frequency determination method (Heating operation control)
8.1.2.2.1. Basic specification
Intake temperature domain is sent to outdoor. Renewal of data every 60 seconds in outdoor.
Domain directions data (intake-setting) transmitted from indoor determine a changed part of frequency.
Then, a directed changed part changes frequency to the present frequency.
Change of frequency may be 1 tap = 1Hz.

The following operation determines change frequency.
The Hzkirikae = present condition frequency *Inclines (calculation)
Inclination = Lapsed time to remote control attainment (min)
Inclination 0-30 30 - 60 60
Inclination coefficient 70% 90% 100%

CS-E9DKEW CU-E9DKE / CS-E12DKE W CU-E12DK E
Values of T1, T2, and T3 depend on remote control setting temperature, as shown in below table. After the adjustment of T1, T2 and T3 values, the operation mode for that particular environment and remote control setting is judged and performed, based on the above operation mode chart, every 30 minutes.
Remote Control Setting Temperature (°C) T1 T2 T3
16 ~ 18 +10 -3 -5 19 ~ 22 +8 -3 -7 23 ~ 26 +7 -3 -7 27 ~ 30 +6 -3 -8
There is a temperature shifting on T1, T2, and T3 if the operation mode judged is changed from Cooling/Soft Dry to Heating or vice verse.
Operation Mode change from Temperature shifts (°C)
Cooling/Soft Dry→Heating -2 Heating→Cooling/Soft Dry +2
Example of operation mode chart adjustment:
From the above table, if remote control setting temperature = 25,
T1 = 25 + 7 = 32; T2 = 25 - 3 = 22; T3 = 25 - 7 = 18
The operation mode chart for this example is as shown in below figure and the operation mode to be performed will depend on indoor intake air temperature and outdoor air temperature at the time when the judgment is made.

Note:
a. UP:
If move from Lo, the fan speed will be shifted to Maximum 1520 rpm.
If move from Maximum, the fan speed no change.
In up zone, 10 rpm is added for every 10s until Maximum 1520 rpm.
b. DOWN:
• The fan speed will be decreased one step every 10 sec. until Minimum 1270 rpm.
c. Current Output Fixed:
Maintain at present fan speed.
d. Instantaneous Maximum:
• Fan speed will be increased to maximum auto fan speed.
e. Temperature in ( ) is for Powerful Mode operation.

C. Fan Motor Control
1. Motor specification
High voltage PWM Motor
2. Feedback Control
a. Number-of-rotations feedback
Immediately after the fan started, rpm is checked and duty is added, and feedback control is performed. For high voltage PWM motor, it is done once every 0.5 second.
b. Offset duty T max/min limit
High voltage PWM motor has maximum offset duty.
(Refer Indoor fan motor control basic rotation speed)
3. Abnormal Detection Control
Conditions:
a. Out of rhythm signal input
b. If feedback number of rotations exceeded #2550 r/min or when less than #50 r/min.
Control: Fans stop
Return: Restart after 5 seconds
* It will not detect the out of rhythm condition within 5s for phase control motor (PWM motor is when duty=0) after start.
A fan stops when condition (1) and (2) happen within 25.0 seconds after fan starting, and if this happens for continuously 7 times, it will not retry.
FM lock processing
4. Restart Prohibition Control
Restart is prohibited within 5s for phase control motor (PWM motor is when duty=0) after fan stop (except re-ON the power supply).

The odor status is arranged as below and it is shifted as follow.
* When COMP is ON 1→2→3
(Shift to 4 when COMP is OFF)
* When COMP is OFF 4→5→6→7→6
(Shift to 1 when COMP is ON)

8.1.8. Outdoor Fan Motor Operation
Outdoor fan motor is operated with one fan speed only. It starts when compressor starts operation and it stops 30 seconds after compressor stops operation.
8.1.9. Airflow Direction
1. There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by vertical vanes).
2. Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat exchanger temperature and intake air temperature) and manual (angles of direction can be adjusted using remote control).

1. Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the angles as stated above. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1 below. When the air conditioner is stopped using remote control, the vane will shift to close position.
2. Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated above and the positions of the vane are as Figure 2 below. When the air conditioner is stopped using remote control, the vane will shift to close position.
8.1.9.2. Horizontal Airflow
1. Automatic horizontal airflow direction can be set using remote control; the vane swings left and right within the angles as stated below. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1 below.
